Nonpoint Source Pollution

Results show that the Algal Turf Scrubber® can be designed to meet the most stringent of TMDL objectives.

Nonpoint source applications that involve nutrient pollutants are especially well suited for the Algal Turf Scrubber® due to the system’s capacity to treat large volumes of water contaminated with relatively low concentrations of pollutants. The Algal Turf Scrubber® is unique in its ability to provide cost-effective treatment even when phosphorus concentrations are below 200 ppb and nitrogen levels are less than 1.5 mg/l.

In Florida, a multi-agency team completed an exhaustive review of over 105 phosphorus control technologies with potential for application in the Lake Okeechobee Watershed. Of the 54 phosphorus control technologies determined to offer “stand-alone” regional capabilities, HydroMentia’s managed aquatic plant system along with treatment wetlands were determined to offer the most proven and cost-effective approaches for phosphorus control.
